How to repair the figure of eight after the rear wheel is impacted by external force?

The location shop suggested changing the camber adjuster, saying it could be adjusted. Axial correction:

Axial correction is to correct the left and right shaking when the rim rotates. Before calibration, fix the wheels on the calibration frame. Please note that the center of the shaft should coincide with the center of the correction frame.

Adjust the movable arm on the correction frame so that the end of the indicator screw is aligned with the outside of the rim, tighten the fixing screw on the movable arm, rotate the rim, check the swing degree and swing section of the rim, tighten the spokes at the back of the swing section with a wrench, and pull the swing section over; You can also relax the spokes inside the swing part to reduce the tension on this side.

Radial correction:

Radial correction is to change the rim from ellipse to concentric circle, observe the distance between the outer edge of the rim and the supporting plate, and understand the radius difference of different rims. First, loosen three to five nuts on both sides of the shortest radius section with a wrench to reduce tension and increase radius.

Then, properly tighten three to five covers on both sides of the long radius part to increase the tension and reduce the radius. After adjustment, slightly approach the adjustment support plate to further correct the spoke tightness at the short radius and the long radius of each part until the radii are basically equal.
